Application January 19, `1953, Serial No. 331,937

` 4 claims. (cl. 274-24) This invention relates to new and usefulimprovements in blood vessel drainagetubes, and has particular referenceto vein and artery drainage and injection tubes such as are used in theprocess of embalming.

In the process of embalming, wherein tubes are inserted in the veins andarteries for removing blood from the circulatory system and injectingother iiuids therein, it is necessary that secure and sealed connectionsmust be made between the veins or arteries and the draining andinjecting tubes used in the process. In the present process for carryingout the operation, the operator inserts the drainage or injection tubeinto the vein or artery and then ties a cord about the vessel to secureit about the tube to prevent leakage. Due to the diiiicult operationsrequired and the inaccessibility of the places where the cord must betied, it has been found most difficult, and in many instances hasresulted in very objectionable leaks which have greatly hindered anddelayed the embalming operations.

The present invention contemplates the provision of an adapter fordrainage tubes whereby the tube may be easily and quickly clamped to ablood vessel after it has been inserted'in said vessel, and which formsa secure and leakproof connection.

Other objects are simplicity and economy of construction, ease andelliciency of operation, and adaptability for use in carrying out all ofthe various drainage and injection operations incident to the embalmingof the human body.

With these objects in view, as well as other objects which will appearin the course of the specification, reference will be had to thedrawing, wherein:

Fig. l is a side elevational view of a blood vessel drainage tube fittedwith an adapter in conformity with the present invention, shown insertedin a blood vessel partially broken away.

Fig. 2 is an enlarged, fragmentary longitudinal sectional view of thedevice as shown in Fig. l.

Fig. 3 is an enlarged, fragmentary, foreshortened plan view of thedevice as shown in Fig. l, with the blood vessel shown partially insection.

Fig. 4 is a sectional view taken on line IV--IV of Fig. 3, wherein theclamping jaws are shown in position for securing the blood vessel to thetube.

Fig. 5 is a view similar to Fig. 4, with the jaws moved to the openposition.

Fig. 6 is a side elevational view of the apparatus shown in use with astraight style arterial tube.

Reference will now be had to the drawing, wherein like referencecharacters refer to similar parts throughout the several views, and thenumeral 10 designates a vein tube having a branch tube 12 and aclean-out rod 14. This vein tube is rounded at its outer end 16 for easyinsertion into the vein 18. To facilitate the insertion of the tube 10the vein is exposed, slit transversely as at 19, and opened to receivethe tube. When the tube has been inserted to the desired depth, theoperator manipulates the clamping means 20, hereinafter described, to

permit the positioning of the vein on tube 10 in the zone of/clamping,where it may be tightly.` clamped to said tube` to prevent any leakageof fluid between the vein and tube.

Clamping means 20 comprises a sleeve member 22 ad-A justably mounted ontube 10 adjacent its rearward end and having a set screw 24 whereby itis secured in fixed clamping members being provided respectively withdepending, substantially semi-cylindrical jaws 32 and 34, said jawsbeing disposed in confronting relation whereby normally to encompasstube 10. Said clamping members are provided respectively with gripmembers 36 and 38 which extend above axle 26 and are adapted to bebrought closer together by thumb and finger pressure to spread jaws 32and 34 apart, as shown in Fig. 5. The jaws are normally urged towardeach other to hug the vein tightly against the tube by means of ahelical spring 40 mounted on axle 26, the opposite end portions of saidspring extending outwardly to rest respectively against the oppositegrip members 36 and 38.

As shown in Figs. 1, 2 and 6 the tube 10 is clear from its forward endto sleeve 22 to permit the easy insertion of said tube into the vein orartery, and furthermore it is to be understood that either straight orcurved tubes may be used with clamping means 20, If necessary, the clampjaws 32 and 34 may be curved to conform to a curved tube.

Reference will now be had to the form shown in Fig. 6, wherein is shownthe clamping means on a straight style arterial tube 42 for the deliveryof the embalming fluid into the circulatory system. The method ofconnecting tubes 10 or 42 to the various pumps, reservoirs, tubes, etc.necessary for carrying out the embalming process is well known in theart, and hence is not here shown or described.

It is apparent that I have invented a blood vessel drainage or injectiontube that is easily and quickly clamped securely in the blood vessel,and one that will definitely preclude all leakage between the tube andblood vessel. While I have shown and described a specific embodiment ofmy device, it is obvious that certain changes of structure and operationcould be made without departing from rthe spirit of the invention asdefined by the scope of the appended claims.

What I claim as new and desire to protect by Letters Patent is:

1. In combination with a rigid tube, a clamping means comprising a shaftfixed to said tube and having a portion disposed in parallel, spacedapart relation to said tube, a pair of clamping members pivoted on saidshaft and each having a jaw portion extending laterally from said shaft,said jaw portions being disposed respectively at opposite sides of saidtube and being shaped to conform generally with the cross-sectionalcontour of said tube, and resilient means urging said jaws toward saidtube.

2. In combination with a rigid cylindrical tube, a clamping meanscomprising a shaft fixed to said tube and having a portion disposed inparallel, spaced apart relation to said tube, a pair of clamping memberspivoted on said shaft and each having a jaw portion extending laterallyfrom said shaft, said jaw portions being disposed respectively atopposite sides of said tube and having a substantially semi-cylindricalform opening toward said tube and with its axis parallel to said tube,and a spring carried by said tube and urging said jaws toward said tube.
